There are quite a few variables named "far" in the kernel, e.g.,
arch/arm64/kvm/inject_fault.c. Coccinelle has special treatment
for "far" as being linkage related, which causes parse errors in
their presence. I've grepped for "far" in the kernel tree, and
haven't noticed where it's used like that, but I could have
missed it.

To reproduce:

cat > test.c << EOF
int main(void)
{
        int far = 0;
        int x;
        x = 10;
        return x;
}
EOF

cat > test.cocci << EOF
@@
identifier x;
@@
- x
+ y
EOF

spatch --sp-file test.cocci test.c --debug --verbose-parsing
